An ejector rod 351 is mounted on the top of the ejector plate 350, and the ejector rod 351 is slidably connected to the bottom inner wall of the drug forming hole 331.
[0026] The specific application scenario of this embodiment is as follows: By setting up a push plate frame 210 and setting an insert plate 211 at the bottom of the push plate frame 210, it is convenient to flexibly select different shapes of upper molds 250 and pressure rods 251 installed on the upper molds 250 according to the different shapes of the medicines to be made. After replacing the tablet template 330, ejector plate 350 and ejector rod 351 installed on the outer wall of the output shaft of the stepper motor 320, it is convenient to make medicines of different shapes, which improves the practicality of the equipment. By setting a mating plug-in connection structure at the connection between the push plate frame 210 and the docking plate 240, and locking the insert plate 211 and the docking plate 240 with horn bolts 220, the work efficiency of changing the upper mold 250 is improved, and the practicality and ease of operation of the equipment are improved.
[0027] Example 2: Figure 1 and Figure 4 The upper mold assembly includes a first cylinder 200 fixedly installed on the outer wall of the bottom end of the top plate 120. The output end of the first cylinder 200 is fixedly connected to the push plate frame 210. The outer wall of the bottom end of the push plate frame 210 is fixedly connected to the insert plate 211 through the snap 212.

The inner wall of the docking plate 240 and the inner wall of the push plate frame 210 are fixedly connected by the horn bolts 220.
[0028] The specific application scenario of this embodiment is as follows: the first cylinder 200 is activated to drive the push plate frame 210 and the upper mold 250 to move downwards synchronously. The upper mold 250 drives the pressure rod 251 to squeeze the top of the medicine forming hole 331. The pressure rod 251 is not set above the area of the powder chamber 130, so as to avoid interference between the pressure rod 251 and the powder chamber 130, so that the medicine forming hole 331 of the pressure rod 251 is squeezed and formed.
[0029] Example 3: As Figures 4-6 The motor mounting bracket 310 is detachably and fixedly installed on the inner wall of the bottom end of the limit card seat 300 by bolts. The stepper motor 320 is fixedly installed on the top of the motor mounting bracket 310. The outer wall of the output shaft of the stepper motor 320 is fixedly connected to the inner wall of the pressure plate template 330 by nut 321. The lifting frame 341 has a hollow structure, and the motor mounting bracket 310 is located in the hollow part inside the lifting frame 341.
[0030] The specific application scenario of this embodiment is as follows: by turning on the stepper motor 320 to drive the tableting template 330 to rotate one revolution, the drug forming hole 331 at the top of the tableting template 330 passes through the powder hopper 130. Under the scraping action inside the powder hopper 130, the powder is automatically added to the drug forming hole 331 under the action of gravity, and the excess powder at the top of the drug forming hole 331 is scraped flat.
[0031] Example 4: Figure 1 and Figure 4 The top outer wall of the base 100 is fixedly connected to the powder hopper 130 via the second leg 131. The bottom of the powder hopper 130 has a hollow structure. The powder hopper 130 is fastened to the top of the tableting template 330. The outer wall of the powder hopper 130 is fixedly connected to the drug delivery pipe 132. The bottom of the internal area of the powder hopper 130 is not provided with a material ejector bar 351.
[0032] The specific application scenario of this embodiment is as follows: by setting the bottom of the powder container 130 to be a hollow structure, the powder in the powder container 130 can fall into the medicine forming hole 331, which facilitates the automatic addition of powder.
[0033] The working principle of this utility model is as follows: When used by those skilled in the art, the external powder filling chamber is connected to the drug delivery pipe 132 through a conduit. The powder is delivered to the powder hopper 130 via the filling structure in the external powder filling chamber. The stepper motor 320 is activated to rotate the tableting template 330 one revolution, causing the drug forming hole 331 at the top of the tableting template 330 to pass through the powder hopper 130. Under the scraping action inside the powder hopper 130, the powder is automatically added to the drug forming hole 331 under gravity, and excess powder on the top surface of the drug forming hole 331 is scraped off. Then, the first cylinder 200 is activated to drive the pusher frame 210 and the upper mold 250 to move downwards synchronously. The upper mold 250 drives the pressure rod 251 to squeeze the top of the drug forming hole 331. No pressure rod 251 is installed above the area of the powder hopper 130. 51, thereby avoiding interference between the pressure rod 251 and the powder hopper 130, so that the medicine is squeezed and formed under the action of the medicine forming hole 331 of the pressure rod 251. The bottom inner wall of the medicine forming hole 331 is provided with a food-grade silicone base, which plays a role in sealing the bottom of the medicine forming hole 331. By opening the second cylinder 340, the pusher 341, the ejector plate 350 and the ejector rod 351 are pushed upward to squeeze the bottom of the food-grade silicone base, so that the formed tablet in the medicine forming hole 331 can be squeezed out. Then, by opening the stepper motor 320 to drive the tablet pressing template 330 to rotate, the medicine is scraped off from the surface of the tablet pressing template 330 under the blocking action of the outer wall of the powder hopper 130 and falls into the external storage bin for storage. After rotating once, the medicine forming hole 331 is automatically filled with medicine powder again for re-pressing.
